I've never seen one. But the settings are all there in DX. You should just need to make the graphics and apply them with the right settings.

When you add DX Player to an object's abilities, then choose configure, it brings up a bunch of DX Player buttons/commands.

Under Default, Fader/Silder, there are bandwidth commands to assign to a slider/fader button that you have pre made. It will ask for the parts and allow you to browse to them. This is a short/sweet explanation from a man who has never made one. But I may soon.

There is probably a way to do it through activex controls too. Dunno.
